Hey there!

First, multiply the second equation by -2 as the problem states. When you multiply the second equation by -2, you get:

A sugar bowl holds 237 grams. You have a one kilogram bag of sugar. Estimate how many bowls of sugar you can fill from the bag.
NeTakaya

Answer:

The required number of bowls are 5.  

Step-by-step explanation:

Given : A sugar bowl holds 237 grams. You have a one kilogram bag of sugar.

To find : Estimate how many bowls of sugar you can fill from the bag?

Solution :

1 bowl can hold 237 gram of sugar.

We have, 1 kg of sugar or 1000 gram of sugar.                

According to question,

237 gram of sugar can hold in 1 bowl.

So, 1 gram of sugar can hold in \frac{1}{237} bowl.

1000 gram of sugar can hold in \frac{1000}{237} bowl.      

1000 gram of sugar can hold in 4.21 bowl.  

Which means, The required number of bowls are 5.

As 4 bowls have 237\times 4=948 grams of sugar.

Sugar left is 1000-948=52 grams

That 52 grams is filled into 5th bowl.
